No standalone package or library explicitly named “Armv7 NEON Codec 1.49.0” exists in official codec projects (FFmpeg, x264, VPX, dav1d, etc.). The version number 1.49.0 strongly suggests a release of the SVT-AV1 encoder (SVT-AV1 uses 1.x.0 semantic versions) or potentially an old libvpx tag. Armv7 NEON optimizations are standard in modern codec builds, but no project marks a release specifically as “Armv7 NEON Codec”.
